Split a string in to words and numbers

I have a string as below.

sil(0.14,0.25) in(0.25,0.82) order(0.82,1.03) to(1.03,1.17) entertain(1.17,1.94) the(1.94,2.04) people(2.04,2.41) who(2.41,2.54) are(2.54,2.6) listening(2.6,3.13) to(3.13,3.开发者_开发技巧29) you, ..........

I have split the string as follow.

sil
0.14
0.25

in
0.25
0.82

order
0.82
1.03

to
1.03
1.17

What I want is to find the difference between the two numbers after each word. eg : sil = 0.25 - 0.14 in = 0.82 - 0.25

Please let me know how to do this task.

Thaks a lot.

Here is my solution :

1. .split() by " " so you can get array like {sil(0.14,0.25), in(0.25,0.82) ...}

2. take each of this array and .parse() by splitting "," and subtract first by second

   private static float parse(String s) {
      String str = s.substring(s.indexOf('(')+1, s.length()-1);
      String[] numbers = str.split(",");
   
      return Float.parseFloat(numbers[1]) - Float.parseFloat(numbers[0]);
   
   }
   
   public static void main(String[] args) {
       String s = "sil(0.14,0.25) in(0.25,0.82) order(0.82,1.03) to(1.03,1.17)            entertain(1.17,1.94) the(1.94,2.04) people(2.04,2.41) who(2.41,2.54) are(2.54,2.6) listening(2.6,3.13) to(3.13,3.29)";
   
       String[] sArray = s.split(" ");
   
       for(String str : sArray){
          String head = str.substring(0, str.indexOf('('));
          System.out.println(head + "=" +parse(str));
       }
   
   }
